Thanks, and yeah id would be too, but when you run cheap oil in these higher performance engines, they smoke alot. I ride this thing almost everyday, lots of fun.
Very generally speaking, piston ported engines need less oil while reed inducted systems need more. There are exceptions.
Running temperatures are also factored in. That is, the hotter it runs-the more oil it needs.
I been kinda looking for one of the Honda air cooled CR's with that same type engine - late 70's all red CR250 or 400 - before they started all the water cooled stuff. Good find for you.
Yah i love the air cooled ones, Just because of the pure simplicity, and with a few mods they are VERY fast. Even though id love to own a liquid,because of the power they make, its just more things to fix lol...
